Hardinge SV150 Spindle Repair
The Hardinge SV150 is a CNC turning center made for 2-axis cutting. It comes equipped with a grease lubricated and pulley driven spindle capable of running up to 6,000 rpm.
Our customer indicated that this Hardinge SV150 spindle was noisy in operation. Upon disassembly and evaluation of the spindle we found that the bearings had failed from contamination (likely coolant). We noted that the bearings still contained grease but it was severely degraded. It was also noted that the encoder ring had several damaged teeth and the mounting bolts were missing. No dimensional deviations were found on this spindle.
The following actions were performed on this Hardinge SV150 spindle:
- Clean all parts of the spindle
- Replace all bolts and o-rings
- Replace encoder ring
- Replace bearings
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
